Sinatra is a light-weight internet utility framework written in Ruby. It supplies a easy and easy-to-use syntax for constructing internet purposes. The framework focuses on being minimalistic, permitting builders to shortly create internet purposes with out coping with extreme boilerplate code and inflexible frameworks like Rails. On this article, we are going to use Sinatra to construct a URL-shortening app that enables customers to enter an extended URL and generate a brief URL that redirects to the unique URL when clicked. The app may even maintain monitor of what number of instances a shortened URL is clicked.
By following this tutorial, you’ll be taught:
– What Sinatra is and why you need to use it
– Tips on how to leverage its highly effective routing options
– Tips on how to work with a database
– Tips on how to add views
To observe together with this tutorial, you have to:
– Ruby put in in your improvement atmosphere
– Sinatra set up (coated on this tutorial)
– Some primary expertise with utilizing Ruby
Now, let’s get began by understanding why we’d like Sinatra within the first place.
Why Sinatra?
Whereas frameworks like Ruby on Rails can deal with nearly any app improvement wants, there are situations the place having a light-weight framework like Sinatra makes extra sense. Sinatra is a superb selection for app improvement as a result of:
1. It is light-weight: Sinatra has minimal dependencies, making it light-weight in comparison with Rails. This enables for extra management over app structure.
2. It has highly effective routing options: Sinatra’s routing system is versatile and expressive, permitting straightforward definition of handlers for frequent HTTP verbs.

Whereas there’s extra to Sinatra than what we have coated right here, these options make it a compelling selection for constructing internet purposes. Subsequent, let’s go over the app we’ll be constructing utilizing Sinatra.
An summary of the app we’ll be constructing:
Our aim is to construct a easy URL-shortening app utilizing Sinatra. Earlier than we dive into the construct course of, let’s perceive how URL shortening works:
1. The person enters an extended URL.
2. The app generates a random string and appends it to a base URL.
